ABOUT GT-R MAINTENANCE
Replacement of brake pads and disc rotors
NISSAN generally recommends to replace all four sets of brake pads and disc rotors at the same time to main-
tain maximum brake performance.
However, replacing only the brake pads may be allowed in some cases (four wheels or only front wheels
depending on the conditions). A GT-R certified technician must inspect the vehicle and determine that only the
brake pads need to be replaced. In this case, replacing all brake pads and disc rotors as a set is not neces-
sary.
Note that the replacement of brake pads and the disc rotors as a set on all four wheels should be performed
when a GT-R certified technician determines that this is the correct repair.
If the inside of the disc rotors are cold during the winter and the surface becomes hot due to a heavy force
being applied repeatedly to the brakes, cracks may occur near the coolant hole on the surface of the disc
rotor. Cracks may also occur due to a heavy force being repeatedly applied to the brakes during high perfor-
mance driving. In these cases it may be necessary to replace the disc rotors or brake pads depending on the
condition of the crack.
EXHAUST MUFFLER AND TRUNK CARPET
Genuine GT-R special exhaust muffler and trunk carpet.
Use only the genuine GT-R special exhaust muffler and trunk carpet.
The GT-R exhaust system is designed to provide the maximum vehicle performance and to protect the vehicle
from high exhaust gas temperatures.
If non-genuine GT-R specification parts are used it is possible that the muffler or other exhaust system parts
will deform and cause damage to the underbody. Non-genuine GT-R specification parts can also affect vehicle
performance and possibly lead to turbocharger, engine or power train related parts including transmission,
damage.
Also, do not remove the trunk carpet from the vehicle for any reason. The carpet insulates the vehicle interior
from the heat of the muffler and from the noise of the transmission.
EXTERIOR PARTS (spoiler, etc.)
Do not modify exterior parts.
The GT-R was developed using a special wind tunnel to help make sure the vehicle is aerodynamically bal-
anced. Additionally, the wind tunnel was used to help make sure cool air flows to the brakes, radiator and other
components. Additions of non-GT-R specific accessory exterior parts can change the air flow over and around
the body. This can affect vehicle balance and cooling of various systems.
For example, if the front bumper is modified, there is a possibility that brake cooling performance may be
reduced due to the decrease of the air flow to the brake system.
Use only GT-R special specification parts.
Front bumper
The shape of the bumper helps pull air into the engine compartment through the front wheel housing to cool
the radiator and brakes. Installing an aftermarket bumper may affect the air flow in the engine compartment
and decrease the brake and engine cooling performance. An aftermarket bumper may also change vehicle
balance by reducing front down force.
Rear spoiler
Installing an aftermarket rear wing may change the down force balance between front and rear of the vehicle.
This can affect the handling characteristics of the vehicle and affect the operation of the ABS and VDC sys-
tems.
CAUTION:
Modifications to exterior parts may affect engine and transmission cooling performance which can
increase the temperature in the engine compartment. This can affect the operation or damage parts
located in the engine compartment.
Dry carbon fiber parts (If so equipped)
The dry carbon fiber parts are made using the same composite method used for race cars. The dry carbon
fiber rear spoiler has a special coating to enhance the feel of the material.
CAUTION:
• Do not use chemical agents (for example: wax, coating agent, compound agent, etc.) on the dry car-
bon fiber parts because they can damage the material. When the carbon fiber parts become dirty,
dilute one cap of mild detergent with a bucket of water and use that mixture to clean the carbon fiber
parts.
• The dry carbon fiber parts may turn yellow due to age deterioration because of the characteristics of
the material. Storing the vehicle outside in direct sunlight for extended periods of time may cause
